The Geological Base Map provides a generalized representation of Austria’s geologic units and tectonic structures. The dataset is based on the analog publication Metallogenetische Karte von Österreich (Weber, 1997) and has been prepared for use in GIS applications without modifying the original geological content. Minor corrections address indexing errors in volcanic rocks west of Güssing. This dataset serves as a reference for regional and supraregional geoscientific analyses and applications.
The service is based on the Geological Base Map 1:500,000 in the national standard model. It serves as the basis for the transformation into the INSPIRE data model (Theme Geology). While this service maintains the full semantic depth of the national model, the INSPIRE version is optimized for cross-border interoperability.
